Descriptions

Cysteamine eye drops is used to treat cystine crystal buildup in the cornea (front part of the eye) of patients with cystinosis. Cystinosis is a hereditary disorder that causes an accumulation of the amino acid cystine within cells, forming crystals that can build up and damage the eyes. This medicine works by removing the extra cystine from the cornea.
